Company as of the close of business as of the anticipated Closing Date (without giving effect to the transactions contemplated hereby, but reflecting any cash that Sellers intend to cause the Company to distribute to Sellers at or immediately prior to closing), which estimated unaudited balance sheet will have been prepared in accordance with GAAP, except for year-end adjustments and the absence of footnotes, and substantially in the form of Exhibit 3.02(a)(2) and (ii) a closing statement, substantially in the form of Exhibit 3.02(a)(1) attached hereto (the Closing Statement), setting forth the Sellers good faith estimate of the Net Working Capital of the Company as of the anticipated Closing Date (the Estimated Closing Net Working Capital), based on the estimated unaudited balance sheet described in clause (i) above, and the estimated adjustment to the Closing Purchase Price pursuant to Section 3.02(b). If Purchaser, in good faith, disputes any portion of the Estimated Closing Net Working Capital, then Purchaser shall notify the Sellers in writing no later than ten (10) days prior to the Closing Date, and the Sellers and Purchaser shall negotiate in good faith in an effort to resolve such disputed portion of the Estimated Closing Net Working Capital prior to the Closing.

(b)(i)If the undisputed portion of the Estimated Closing Net Working Capital is less than zero (0), then the Closing Purchase Price shall be reduced by an amount equal to such deficiency; and if the undisputed portion of the Estimated Closing Net Working Capital is greater than zero (0), the Closing Purchase Price shall be increased by an amount equal to such excess. Such adjustment shall be calculated based on the Sellers good faith estimate of Net Working Capital of the Company at the Closing Date, set forth in the Closing Statement delivered to Purchaser pursuant to paragraph (a) above, and any dispute notice timely delivered by the Purchaser to Sellers, and any resolution of such dispute, if any such resolution is reached by the parties pursuant to the negotiations contemplated by Section 3.02(a). The Sellers shall provide to Purchaser such data and information as Purchaser may reasonably request supporting the amounts reflected in the Closing Statement, and Purchaser shall provide to Sellers such data and information as Sellers may reasonably request supporting Purchasers dispute.

(ii)(A) In the event that the Closing Date occurs prior to the Target Closing Date, an amount equal to the PPA Adjustment Amount shall be added to the Closing Purchase Price, (the Early Adjustment Amount, it being understood that such amount may be a positive or negative number) and (B) in the event that the Closing Date occurs after the Target Closing Date, an amount equal to the PPA Adjustment Amount shall be subtracted from the Closing Purchase Price, (the Later Adjustment Amount, it being understood that such amount may be a positive or negative number).

The Closing Purchase Price, as so adjusted by the Early

19

Adjustment Amount or the Later Adjustment Amount, as the case may be, and the other adjustments thereto under this Article III, shall be paid in accordance with Section 3.01.

[CONFIDENTIAL TREATMENT REQUESTED]. Purchasers accountants shall consult with the Sellers accountants in connection with the preparation of the Final Closing Balance Sheet and the Final PPA Adjustment Amount, and each Party shall permit the other Parties accountants, as reasonably required, to review and have access to records, and to make copies of all work papers, schedules and calculations, required or used in the preparation of the Final Closing Balance Sheet and the Final PPA Adjustment Amount, all at the earliest practicable date. Sellers shall cause their accountants to cooperate with Purchaser and Purchasers accountants in connection with the preparation of the Final Closing Balance Sheet and the Final PPA Adjustment Amount, including by responding promptly to any requests by Purchaser or Purchasers accountants for information reasonably required to prepare such Final Closing Balance Sheet and the Final PPA Adjustment Amount. For the avoidance of doubt, to the extent any items, including trailing account payables, are used to prepare both the Final Closing Balance Sheet and the Final PPA Adjustment Amount, it is the intent of the Parties that none of the Parties shall receive any windfall as a result of redundancy (double-counting) that may be applied to both the Final Closing Balance Sheet and the Final PPA Adjustment Amount and that each of the same may be adjusted with regard to such redundant item(s) to avoid such windfall or double-counting.

(d)When the Purchaser delivers the Final Closing Balance Sheet and the Final PPA Adjustment Amount, Purchaser shall also deliver to the Sellers a certificate, substantially in the form of Exhibit 3.02(a)(3), containing the Purchasers calculations (the Purchasers Proposed Calculations), of (i) the Net Working Capital of the Company as of the Closing Date (the Closing Date Net Working Capital) (based on the Final Closing Balance Sheet), (ii) the Final PPA Adjustment Amount, and (iii) the adjustment to the Closing Purchase Price that should have been made on the Closing Date pursuant to Section 3.02(b). Within thirty (30) days after receipt of the Final Closing Balance Sheet, the Final PPA Adjustment Amount and the accompanying certificate containing the Purchasers Proposed Calculations, Sellers shall notify the Purchaser in writing of their agreement or disagreement, as the case may be, with (x) the Final Closing Balance Sheet and the accuracy of any of the Purchasers Proposed Calculations,

(y) the Final PPA Adjustment Amount and the Purchasers calculations thereof, and (z) if Sellers so disagree with the Final Closing Balance Sheet and the accuracy of any of the Purchasers Proposed Calculations and/or the Final PPA Adjustment Amount and the accuracy of Purchasers calculation thereof, then such written notice shall also include the Sellers proposed alternative calculations (the Sellers Proposed Calculations) of the Closing Date Net Working Capital, the Final PPA Adjustment Amount and the adjustments to the Closing Purchase Price that should have been made on the Closing Date pursuant to Section 3.02(b). If Sellers fail to provide such written notice (including Sellers Proposed Calculations and proposed calculations with regard to the Final PPA Adjustment Amount) within such thirty (30) day period, then Sellers shall be deemed to have accepted the Final Closing Balance Sheet and the Purchasers Proposed Calculations and the Final PPA Adjustment Amount and Purchasers calculations thereof. If Sellers timely deliver such written notice to Purchaser, then Sellers and Purchaser shall negotiate in good faith to resolve any such disagreement with respect to the Final Closing Balance Sheet, the Purchasers Proposed Calculations, the Final PPA Adjustment Amount and the Purchasers calculation of the Final PPA Adjustment Amount. If the Purchaser and the Sellers are not able to resolve such dispute within thirty (30) days after the Purchasers receipt of Sellers Proposed Calculations and/or Sellers calculation of the Final PPA Adjustment Amount, then the Sellers and Purchaser retain the Independent Accounting Firm to resolve the remaining disputed items (the Remaining Disputed Items), within thirty (30) days after the retention of the Independent Accounting Firm, by conducting its own review and test of (i) each of the Purchasers Proposed Calculations and the Sellers Proposed Calculations, including the balance sheets, expenses statements and other records on which each such calculations were based, and thereafter selecting either Purchasers Proposed Calculations of the Remaining Disputed Items or the Sellers Proposed Calculations of the Remaining Disputed Items or an amount in between the two and/or (ii) each of the Purchasers calculations and the Sellers calculations with regard to the Final PPA Adjustment Amount, including the expenses statements and other records on which each such calculations were based, and thereafter selecting either Purchasers calculations of the Remaining Disputed Items or the Sellers calculations of the Remaining Disputed Items or an amount in between the two. Purchasers accountants and Sellers accountants shall be each entitled to consult with the Independent Accounting Firm with respect to any of the foregoing and the Independent Accounting Firms calculations thereof, and each Party shall permit the other Parties accountants, as reasonably required, to review and have access to records, and to make copies of all work papers, schedules and calculations, required or used by the Independent Accounting Firm in connection with the foregoing determination. Purchaser and the Sellers agree that they shall be bound by the determination of the Remaining Disputed Items by the Independent Accounting Firm. [CONFIDENTIAL TREATMENT REQUESTED].

(e)Upon the determination, pursuant to Section 3.02(d) above, of the Final Closing Balance Sheet, the Closing Date Net Working Capital and, as the case may be, the Early Adjustment Amount or the Later Adjustment Amount, and the final adjustments to the Closing Purchase Price pursuant to Section 3.02(b), the Closing Purchase Price shall be recalculated as follows (the Final Adjustment):

(iv)Each Party shall cooperate in assuring that Taxes that are the responsibility of Sellers pursuant to this Section 7.03(a) are paid by Sellers, and that Taxes that are the responsibility of the Purchaser pursuant to this Section 7.03(a) are paid by the Purchaser.

No such Tax Returns shall be amended without the prior written consent of Sellers.

(ii)Purchaser shall prepare and file all Tax Returns required to be filed by the Company for any taxable period ending after the Closing Date. Any such Tax Return for a Straddle Period shall be prepared on a basis consistent with past practices unless otherwise required by Applicable Law. Not later than sixty (60) days prior to the filing of a Tax Return of the Company for a Straddle Period, Purchaser shall deliver a copy of such Tax Return to Sellers for their review and comment. Sellers shall provide to Purchaser any comments Sellers may have with respect to any such Tax Return within twenty (20) days of receiving such Tax Return. Sellers and Purchaser shall attempt to mutually resolve any disputes regarding any such Tax Returns within five (5) days of Purchaser receiving Sellers comments, provided that if any such dispute cannot be resolved within such time period, the dispute shall be submitted to the Independent Accounting Firm for resolution (in which case the provisions set forth in Section 3.02 with respect to resolution of disputed items by the Independent Accounting Firm shall apply) and the determination rendered by an Independent Accounting Firm mutually agreed to Purchaser and Sellers shall be final and binding on the Parties for all purposes and such Tax Return shall be filed in a manner that is consistent with such determination. Not later than thirty (30) days after filing any Tax Return of the Company for a Straddle Period, Purchaser shall deliver a copy of such Tax Return as filed to Sellers.

(iii)Sellers and Purchaser shall reasonably cooperate, and shall cause their respective Affiliates and Representatives reasonably to cooperate, in preparing and filing all Tax Returns, including maintaining and making available to each other all records that are necessary for the preparation of any Tax Returns that the other is required to file under this Section 7.03 and in resolving any disputes between the Parties with respect to such Tax Returns.

(iv)Purchaser shall notify Sellers in writing upon receipt by Purchaser, the Company, or any of Purchasers Affiliates of a notice of any pending or threatened United States federal, state or local Tax audits or assessments which may materially affect the Tax Liabilities for which either Seller is liable pursuant to Section 7.03(a); provided, that failure to comply with this provision shall not affect either Sellers

obligation with respect to such Tax Liabilities except to the extent such failure materially impairs such Sellers ability to contest any such Tax Liabilities.

(v)Subject to Section 7.03(b)(vi), each Seller shall have the sole right to represent the Companys interests in any Tax audit or administrative or court proceeding relating solely to Tax Liabilities for which such Seller is liable pursuant to Section 7.03(a) and which relate to Pre-Closing Periods, and to employ counsel of such Sellers choice at such Sellers expense; provided, however, that such Seller shall have no right to represent the Companys interests in any Tax audit or administrative or court proceeding unless such Seller shall have first notified Purchaser in writing (i) of such Sellers intention to do so and (ii) that such Seller agrees with Purchaser that, as between Purchaser and such Seller, such Seller shall be liable for any Taxes and Losses relating to Taxes that result from such audit or proceeding; provided, further, that Purchaser and its Representatives shall be permitted, at Purchasers expense, to be present at, and participate in, any such audit or proceeding. Notwithstanding the foregoing, without the prior written consent of Purchaser, which consent may not be unreasonably withheld, delayed or conditioned, neither of the Sellers nor any Affiliate of either Seller shall be entitled to settle, either administratively or after the commencement of litigation, any claim for Taxes which could materially adversely affect the liability for Taxes for which Purchaser is responsible under Section 7.03(a).

(vi)Sellers and Purchaser shall jointly control any Tax audit or administrative or court proceeding relating to Tax Liabilities for a Straddle Period, with any disputes as to the conduct of such audit or administrative or court proceeding being resolved in the manner set forth as follows. The objecting Party shall notify the other Party in writing of the area or areas of disagreement. If the Parties are unable to resolve their dispute within twenty (20) days, the matter shall be referred to a certified accountant or tax attorney (Tax Advisor) selected by both Parties. The decision of the Tax Advisor shall be binding on all Parties. The Tax Advisors fees shall be shared equally between Sellers, on the one hand, and Purchaser on the other hand. No Party or its Affiliates shall take a position on any Tax Return, or in any Tax audit or administrative or court, that is in any manner inconsistent with such determination, without the prior written consent of the other Party. Purchaser shall have the sole right to represent the Companys interests in any Tax audit or administrative or court proceeding relating to Tax Liabilities other than any proceeding for a Straddle Period and any proceeding in respect of which either Seller has the representation right pursuant to Section 7.03(b)(v) and to employ counsel of Purchasers choice at Purchasers expense.

(vii)Nothing herein shall be construed to impose on Purchaser or either Seller any obligation to defend the Company in any Tax audit or administrative or court proceeding.

(viii)Sellers and Purchaser shall reasonably cooperate, and shall cause their respective Affiliates and Representatives reasonably to cooperate, in connection with any

and promptly provide Sellers with copies of all drafts of such Phase I report obtained pursuant to Section 9.02(i) and the final report. Purchaser shall advise Sellers if there are any items on such Phase I report to which Purchaser objects no later than ninety (90) days after the date of this Agreement. Seller shall have the right to update Schedule 4.02(n) based on the results of such title commitment and survey and Purchasers objections to any items in such title commitment and survey (including any items that come within the proviso of clause (f) of the definition of Permitted Liens) and Schedule 4.02(i) based on the results of such Phase I report and Purchasers objections to any items in such Phase I report. Any Disclosure Schedule Update shall not be deemed to be an acknowledgment or representation that such Disclosure Schedule Update is material, to establish any standard of materiality or to define further the meaning of such terms for purposes of this Agreement. In no event shall any Disclosure Schedule Update after the date of this Agreement be deemed to cure any inaccuracy or breach of any representation or warranty by either Seller in this Agreement as of the date of this Agreement.

(b)If (i) Purchaser has the right to terminate the Agreement pursuant to Section 13.01(c) as a result of the breach of the representation and warranty to which the Disclosure Schedule Update relates, so long as such breach is not the result of fraud or intentional misconduct by the Sellers, and (ii) Purchaser does not exercise such right within twenty (20) Business Days of delivery of the Disclosure Schedule Update or the expiration of the cure period under Section 13.01(c), whichever is later, then, and only then, such Disclosure Schedule Update will be deemed to have amended the appropriate Schedule or Schedules as of the date of this Agreement, to have qualified the representations and warranties as of the date of this Agreement, and to have cured any misrepresentation or breach of warranty that otherwise might have existed hereunder by reason of the existence of such matter, and Purchaser shall not have any right to indemnity for such claims under this Agreement; provided, however, that with regard to any Disclosure Schedule Update that results in the breach of the representation and warranty to which such Disclosure Schedule Update relates and gives rise to Purchasers right to terminate this Agreement pursuant to Section 13.01(c), the Parties may, in each of the Parties sole discretion, enter into such amendment or supplement to this Agreement as may be necessary or desirable to address such event or condition relating to such Disclosure Schedule Update for the purposes of consummating the transactions contemplated herein on the Closing Date.

(c)Notwithstanding anything in this Section 8.04 to the contrary, in no event shall any Disclosure Schedule Update from either Seller be deemed to have amended any of the Excluded Update Schedules, to have qualified the representations and warranties relating to any of the Excluded Update Schedule as of the date of this Agreement, or to have cured any misrepresentation or breach of warranty relating to any of the Excluded Update Schedules that otherwise might have existed hereunder by reason of the existence of such matter.

So long as the Indemnifying Party, at the Indemnifying Partys cost and expense, (i) has undertaken the defense of, and assumed full responsibility for all indemnified liabilities with respect to, such claim, (ii) is contesting such claim in good faith through appropriate proceedings and (iii) has taken such action (including the posting of a bond, deposit or other security) as may be necessary to prevent any action to foreclose a Lien against or attachment of the property of the Indemnified Party for payment of such claim, the Indemnified Party shall not pay or settle any such claim; provided, however, that, the Indemnified Party shall have the right to pay or settle any such claim if it has waived in writing any right to indemnity by the Indemnifying Party for such claim; and, provided, further, that, if within ten (10) days of such notice from the Indemnified Party, the

61

CONFIDENTIAL TREATMENT REQUESTED FOR PORTIONS OF THIS DOCUMENT. PORTIONS FOR WHICH CONFIDENTIAL TREATMENT IS REQUESTED ARE DENOTED BY [CONFIDENTIAL TREATMENT REQUESTED]. MATERIAL OMITTED HAS BEEN FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION.

Indemnifying Party does not notify the Indemnified Party that it elects (at the Indemnifying Partys cost and expense) to undertake the defense thereof and assume full responsibility for all indemnified liabilities with respect thereto, or gives such notice and thereafter fails to contest such claim in good faith or to prevent action to foreclose a Lien against or attachment of the Indemnified Partys property as contemplated above, the Indemnified Party shall have the right, at the Indemnifying Partys expense, to contest, settle or compromise such claim and the Indemnified Party shall not thereby waive any right to indemnity for such claim under this Agreement.

(iii)Limitations on Settlement. No Indemnifying Party will consent to any settlement, compromise or discharge (including the consent to entry of any judgment) of any such claim without the Indemnified Partys prior written consent (which consent will not be unreasonably withheld or delayed), provided, that, if the Indemnifying Party assumes the defense of any such claim, the Indemnified Party will agree to any settlement, compromise or discharge of such claim which the Indemnifying Party may recommend and which by its terms obligates the Indemnifying Party to pay the full amount of Losses in connection with such claim and releases the Indemnified Party and its Affiliates from liability in connection with such claim; provided, however, that the Indemnified Party may refuse to agree to any such settlement, compromise or discharge (x) that provides for injunctive or other non-monetary relief affecting the Indemnified Party or any of its Affiliates or (y) that, in the reasonable opinion of the Indemnified Party, would otherwise adversely affect the Indemnified Party. Whether or not the Indemnifying Party shall have assumed the defense of such claim, the Indemnified Party will not admit any liability with respect to, or settle, compromise or discharge (including the consent to entry of any judgment with respect to), any such claim without the prior written consent of the Indemnifying Party (which consent will not be unreasonably withheld or delayed).

(b)Procedure for Other Claims. Any claim on account of Losses for which indemnification is provided under this Agreement, which does not involve a claim of a third party, will be asserted by written notice (setting forth in reasonable detail the facts or circumstances that allegedly give rise to such claim and, to the extent known, the amount thereof) given by the Indemnified Party to the Indemnifying Party from whom such indemnification is sought, which notice shall be given promptly after such Indemnified Party obtains actual knowledge of the existence of such claim. The failure or delay of the Indemnified Party to deliver prompt written notice of a claim shall not affect the indemnity obligations of the Indemnifying Party hereunder, except to the extent the Indemnifying Party was actually disadvantaged by such failure or delay in delivery of notice of such claim.

(c)Subrogation. In the event of payment in full by an Indemnifying Party to any Indemnified Party in connection with any claim (an Indemnified Claim), such Indemnifying Party will be subrogated to and will stand in the place of such Indemnified Party as to any events or circumstances in respect of which such Indemnified Party may have any right or claim

62

CONFIDENTIAL TREATMENT REQUESTED FOR PORTIONS OF THIS DOCUMENT. PORTIONS FOR WHICH CONFIDENTIAL TREATMENT IS REQUESTED ARE DENOTED BY [CONFIDENTIAL TREATMENT REQUESTED]. MATERIAL OMITTED HAS BEEN FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION.

relating to such Indemnified Claim against any claimant or plaintiff asserting such Indemnified Claim or against any other Person. Such Indemnified Party will cooperate with such Indemnifying Party in a reasonable manner, and at the cost and expense of such Indemnifying Party, in prosecuting any subrogated right or claim.

SECTION 12.05Survival and Time Limitation. The terms and provisions of this Agreement shall survive the Closing of the transactions contemplated hereunder. Notwithstanding the foregoing, after the Closing, any claim by any Purchaser Indemnified Party that either Seller is liable to such Purchaser Indemnified Party under the terms of this Agreement for breach of any representations or warranties of such Seller must be made in writing and given to such Seller (or not at all) on or prior to the date that is [CONFIDENTIAL TREATMENT REQUESTED] after the Closing Date, except that (a) any claims for breach of the Specified Representations shall survive the Closing [CONFIDENTIAL TREATMENT REQUESTED], (b) any claims for breach of the representations and warranties in Sections 4.02(j) (Taxes) and 4.02(k) (Employee Benefits) shall survive the Closing until the date that is [CONFIDENTIAL TREATMENT REQUESTED] past the expiration of the applicable statute of limitations, and (c) there shall be no such time limitation or survival period for any fraud or intentional misconduct.

SECTION 12.06Further Indemnity Limitations.

(a)Insurance Proceeds. The amount of any indemnifiable Losses shall be reduced to the extent of any (i) insurance proceeds actually received by such Indemnified Party with respect to such Loss less any self insurance retention amount, deductibles paid and any reasonably foreseeable increases in premiums, in each case relating to such Losses and (ii) any payment actually received by an Indemnified Party from a third party with respect to such Loss.

(b)Mitigation. Notwithstanding anything to the contrary contained herein, upon becoming aware of a Loss for which it seeks indemnification the Indemnified Party will take all commercially reasonable steps to mitigate all Losses relating to a claim, including availing itself of any defenses, limitations, rights of contribution, claims against third Persons and other rights at law or equity, and will provide such evidence and documentation of the nature and extent of the claim as may be reasonably requested by the Indemnifying Party.

(c)Materiality. For purposes of determining the amount of Losses resulting from a breach of a representation, warranty, or covenant under this Agreement (but not for the purpose of determining whether or not such representation, warranty, or covenant has been breached for the purposes of Sections 12.01 and 12.02), the amount of such Losses shall be determined without reference to any materiality or Material Adverse Effect qualification in such representation, warranty, or covenant.

SECTION 12.07Sole and Exclusive Remedy. From and after the Closing, the indemnification provisions of this Article XII shall be the sole and exclusive remedy of each Party (including the Seller Indemnified Parties and the Purchaser Indemnified Parties) (i) for any breach of any Partys representations, warranties, covenants or agreements contained in this

63

CONFIDENTIAL TREATMENT REQUESTED FOR PORTIONS OF THIS DOCUMENT. PORTIONS FOR WHICH CONFIDENTIAL TREATMENT IS REQUESTED ARE DENOTED BY [CONFIDENTIAL TREATMENT REQUESTED]. MATERIAL OMITTED HAS BEEN FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION.

Agreement or (ii) otherwise with respect to this Agreement or the transactions contemplated hereby with respect to the Company, other than in the case of (i) and (ii) instances of fraud or intentional misconduct or claims for non-monetary relief with respect to the enforcement of Section 6.02 or 8.03. In furtherance of the foregoing, each Party hereby waives, to the fullest extent permitted under Applicable Law, any and all rights, claims and causes of action it may have against another Party hereunder or under Applicable Law with respect to the claims described in clauses (i) and (ii) above, other than instances of fraud or intentional misconduct or claims for non-monetary relief with respect to the enforcement of Section 6.02 or 8.03.

SECTION 12.08Waiver of Damages. Notwithstanding anything to the contrary contained in this Agreement, the Sellers and Purchaser agree that the recovery by any Indemnified Party of any damages suffered or incurred by such Indemnified Party as a result of any breach by another Party of any of its obligations under this Agreement shall be limited to the Losses suffered or incurred by an Indemnified Party as a result of the breach by the breaching Party of its obligations hereunder. Except with respect to any third party claims against the Indemnified Party and in instances of fraud or intentional misconduct, in no event shall the breaching Party be liable to an Indemnified Party for any indirect, consequential, special, exemplary or punitive damages.

SECTION 12.09Additional Limitations.

For the avoidance of doubt, this Article XII, including Section 12.07, shall have no application with respect to claims between Fox OP and Fox River.

SECTION 12.10Special Indemnity.

Prior to Closing, Sellers shall use commercially reasonable efforts to obtain and deliver to Purchaser (a) a fully executed copy of [CONFIDENTIAL TREATMENT REQUESTED] described in [CONFIDENTIAL TREATMENT REQUESTED] 3 on Schedule 4.02(n), and (b) an assignment instrument [CONFIDENTIAL TREATMENT REQUESTED] pursuant to which the original grantor assigned the [CONFIDENTIAL TREATMENT REQUESTED] described in [CONFIDENTIAL TREATMENT REQUESTED] 11 on Schedule 4.02(n) [CONFIDENTIAL TREATMENT REQUESTED] to the current grantor under the [CONFIDENTIAL TREATMENT REQUESTED], and an estoppel certificate or similar written assurance executed by the current grantor under the [CONFIDENTIAL TREATMENT REQUESTED] in form and substance reasonably acceptable to Purchaser [CONFIDENTIAL TREATMENT REQUESTED]. In the event that Sellers obtain and deliver the [CONFIDENTIAL TREATMENT REQUESTED], the [CONFIDENTIAL TREATMENT REQUESTED] or the [CONFIDENTIAL TREATMENT REQUESTED] prior to Closing, and any of such are not reasonably acceptable to Purchaser, then Purchaser shall have the right to terminate this Agreement by notice to Sellers.In the event Sellers fail to obtain and deliver to Purchaser the [CONFIDENTIAL TREATMENT REQUESTED],the [CONFIDENTIAL TREATMENT REQUESTED] or the [CONFIDENTIAL TREATMENT REQUESTED]on or prior to the Closing Date, from and after the Closing, each Seller shall indemnify, defend, reimburse and hold harmless the Purchaser Indemnified Parties, on a several and not a joint basis, from and against any and all reasonable Losses actually

incurred by any Purchaser Indemnified Party, acting consistent with Prudent Industry Practices and in a manner consistent with the actions of such Purchaser Indemnified Party or other utilities acting under similar circumstances, as a result of, in connection with, relating to or arising out of (y) failure of Company to hold a [CONFIDENTIAL TREATMENT REQUESTED] for [CONFIDENTIAL TREATMENT REQUESTED] 3 on Schedule 4.02(n), with no further consideration due, and otherwise on terms substantially similar to the [CONFIDENTIAL TREATMENT REQUESTED] for [CONFIDENTIAL TREATMENT REQUESTED] 5 on Schedule 4.02(n) (in the event that Sellers fail to deliver the [CONFIDENTIAL TREATMENT REQUESTED] prior to the Closing Date), or (z) assignment to the current grantor of the [CONFIDENTIAL TREATMENT REQUESTED] having caused or resulting in a material change in terms or termination of the [CONFIDENTIAL TREATMENT REQUESTED] (in the event that Sellers fail to deliver the [CONFIDENTIAL TREATMENT REQUESTED] prior to the Closing Date), or any Company monetary breach or default under the [CONFIDENTIAL TREATMENT REQUESTED] (in the event that Sellers fail to deliver the [CONFIDENTIAL TREATMENT REQUESTED] prior to the Closing Date). The foregoing indemnity shall be effective notwithstanding any disclosures in the Disclosure Schedules as of the date of this Agreement.

ARTICLE XIII

TERMINATION AND REMEDIES

SECTION 13.01Termination of Agreement. No Party may terminate this Agreement if the event allowing termination is the result of such Partys material breach of this Agreement. Subject to the foregoing, this Agreement and the transactions contemplated hereby may be terminated at any time prior to the Closing:

(a)by the mutual written consent of each Seller and Purchaser;

(b)by either Seller, if (i) Purchaser fails to comply with any of its covenants or agreements contained herein, or breaches any of its representations and warranties contained herein, which failure to comply or breach is not cured within thirty (30) days after receipt by Purchaser from either Seller of written notice of such failure to comply or breach, and such failure to comply or breach would result in a failure to satisfy the conditions to Closing set forth in Section 9.01, or (ii) any of the Purchaser Regulatory Approvals, the Seller Regulatory Approvals and the FERC Approval shall have been obtained on terms and conditions that are materially adverse to the interests of either of the Sellers;

(c)by Purchaser, if (i) either Seller fails to comply with any of its covenants or agreements contained herein, or breaches any of its representations and warranties contained herein, which failure to comply or breach is not cured within thirty (30) days after receipt by the Sellers from Purchaser written notice of such failure to comply or breach, and such failure to comply or breach would result in a failure to satisfy the conditions to Closing set forth in Section 9.02; or (ii) any of the Purchaser Regulatory Approvals (except the Purchaser Regulatory Approval contemplated by clause (2) of the definition of Wisconsin PSC Approval), the Seller

65

Regulatory Approvals and the FERC Approval shall have been obtained on terms and conditions that are materially adverse to the interests of Purchaser;

(d)by either Seller or Purchaser, if a Governmental Authority shall have issued an order, decree or ruling or taken any other action (which order, decree or ruling the parties hereto shall use their commercially reasonable efforts to lift), which permanently restrains, enjoins or otherwise prohibits the transactions contemplated by this Agreement and which order, decree, ruling or other action is not subject to appeal;

(e)by Purchaser or either Seller, notice to the others, at any time if Closing does not occur on or before December 28, 2013 (the Closing Deadline);

(f)by Purchaser, if [CONFIDENTIAL TREATMENT REQUESTED], and the same is not cured (including by [CONFIDENTIAL TREATMENT REQUESTED], as reasonably determined by Purchaser) within thirty (30) days after receipt by the applicable Seller from Purchaser of written notice specifying particularly such decline, and such decline would result in a failure to satisfy the conditions to Closing set forth in Section 9.02(e);

(g)by Purchaser, if by November 1, 2012, the Lender Consent has not been obtained;

(h)by either Seller, if Purchaser terminates the New Tolling Agreement in accordance with its terms; or

(i)by Purchaser, as set forth in Section 12.10.

SECTION 13.02Effect of Termination. In the event of termination of this Agreement by a Seller or Purchaser pursuant to Section 13.01, written notice thereof shall promptly be given by the terminating Party to the other Parties, and this Agreement shall thereupon terminate. Following any such termination, Purchaser and the Sellers will continue to be bound by their obligations set forth in Sections 6.02, 8.03 and 8.06(d), Sections 12.08 and 13.03(d) and Article XIV. If this Agreement is terminated as provided herein, (a) all filings, applications and other submissions made to any Governmental Authority shall, to the extent practicable, be withdrawn from the Governmental Authority to which they were made, and (b) for the avoidance of doubt, the Existing Tolling Agreement and New Tolling Agreement shall remain in full force and effect in accordance with its terms.

SECTION 13.03Remedies.

(c)Election of Remedies.

Except as expressly provided in this Agreement, all rights and remedies hereunder shall be cumulative. Except as otherwise provided by Applicable Law, no delay or forbearance by a Party in the exercise or enforcement of any right or remedy hereunder shall be deemed a waiver by such Party of its right hereunder to exercise or enforce such right or remedy.

ARTICLE XIV

OTHER PROVISIONS

SECTION 14.01Seller Liability. The Parties hereby recognize and agree that, even where not otherwise explicitly stated in this Agreement, the liability of each Seller under this Agreement (including with respect to the indemnification provisions contained in Article XII) is intended to be several, and not joint, with [CONFIDENTIAL TREATMENT REQUESTED] of any such liabilities; provided, however that this Section 14.01 shall have no application with respect to (i) breaches of this Agreement by one Seller only, in which case only such Seller shall have liability hereunder, and (ii) breaches of any representation and warranties made only by one Seller under Article IV, in which case only the Seller breaching the representations and warranty shall have liability hereunder. Representations and Warranties under Section 4.01 relating to Fox OP are made by Fox OP only, and not by Fox River; and Representations and Warranties under Section 4.01 relating to Fox River are made by Fox River only and not Fox OP. Representations and Warranties under Section 4.02 that are made to Sellers Knowledge or Sellers Actual Knowledge and are inaccurate shall be deemed to have been breached by both Sellers even though only one Seller had Sellers Knowledge or Sellers Actual Knowledge.

SECTION 14.02Counterparts. This Agreement may be executed in one or more counterparts (including by means of telecopied signature pages), all of which, taken together,

This Agreement and the rights and obligations of the Parties hereunder and the transactions contemplated hereby shall be governed by, enforced and interpreted in accordance with the laws of the State of Wisconsin without regard to principles of conflicts of laws. Each of the Parties hereby irrevocably and unconditionally submits to the jurisdiction of any court of the State of Wisconsin located in Milwaukee, Wisconsin and any federal court located in the Eastern District of Wisconsin with respect to any proceeding relating to this Agreement. Further, each of the Parties hereby irrevocably and unconditionally waives any objection or defense that it may have based on improper venue or forum non conveniens to the conduct of any such proceeding in any such courts. The Parties agree that any or all of them may file a copy of this paragraph with any court as written evidence of the knowing, voluntary and bargained agreement between the Parties irrevocably to waive any objections to venue or to convenience of forum. Each of the Parties agrees that a final judgment in any such action or proceeding will be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Applicable Law.

SECTION 14.04Entire Agreement. This Agreement and the Schedules and Exhibits hereto contain the entire agreement between the Parties with respect to the subject matter hereof and supersede any prior written or oral agreements, understandings, representations or warranties between the Parties.

SECTION 14.05Notices. All notices hereunder shall be sufficiently given for all purposes hereunder if in writing and delivered personally, sent by documented overnight delivery service or, to the extent receipt is confirmed, by United States mail, or facsimile to the appropriate address or number as set forth below.

No assignment of this Agreement

will relieve the assigning or designating party of its obligations hereunder. Subject to this Section 14.06, this Agreement shall be binding upon and inure to the benefit of the Parties and their successors and assigns.

(b)Purchaser may assign, including by operation of law, its rights and obligations under this Agreement to (i) any Affiliate of Purchaser upon prior written notice to the Sellers or (ii) Financing Parties as collateral security to such Financing Parties, as more fully set forth in Section 14.06(c) below; provided that any such assignment under (i) or (ii) shall not relieve Purchaser of any of its obligations under this Agreement.

(c)In connection with any collateral assignment by Purchaser of this Agreement to Financing Parties as set forth in Section 14.07(b) above, Sellers agree to enter into an agreement in form and substance reasonably satisfactory to Sellers directly with the Financing Parties and Purchaser under which Sellers shall consent to such assignment and will agree to other customary and reasonable provisions for the benefit of the Financing Parties, including, without limitation, reasonable provisions under which the Financing Parties or their designees (i) may assume or transfer the rights of Purchaser under this Agreement, (ii) shall be entitled to receive from Sellers copies of certain notices relating to breaches by the Purchaser and other similar matters hereunder that Sellers might provide to Purchaser, (iii) obtain Sellers agreement, subject to any rights Sellers may have hereunder, including any right of offset, to make all payments due to Purchaser under this Agreement to an account designated by the Financing Parties and (iv) shall be provided other customary or related benefits or protections as reasonably requested by the Financing Parties to support such financing (not including in any event amendments to the Company Contracts), in each case reasonably acceptable to Sellers and at no actual cost to Sellers.

SECTION 14.07Amendments and Waivers. This Agreement may not be modified or amended except by an instrument or instruments in writing signed by each of the Parties. The Sellers may together waive compliance by Purchaser, and Purchaser may waive compliance by the Sellers, with any term or provision of this Agreement on the part of such Party or Parties to be performed or complied with, only by an instrument in writing. The waiver by a Party of a breach of any term or provision of this Agreement shall not be construed as a waiver of any subsequent breach.

SECTION 14.08Schedules and Exhibits. All Schedules and Exhibits hereto that are referred to herein are hereby made a part hereof and incorporated herein by such reference. Information set forth in the Schedules is included solely for informational purposes, is not an admission of liability with respect to the matters covered by the information, and may not be required to be disclosed, pursuant to this Agreement. The specification of any dollar amount in the representations and warranties contained in this Agreement or the inclusion of any specific item in the Schedules is not intended to imply that such amounts (or higher or lower amounts) are or are not material, and no Party shall use the fact of the setting of such amounts or the fact of the inclusion of any such item in the Schedules in any claim, dispute or controversy as to whether any obligation, item or matter not described herein or included in a Schedule is or is not

material for purposes of this Agreement. Any disclosure in a particular Schedule shall be deemed and understood to be disclosure in each other Schedule to which the applicability of such disclosure is readily apparent on its face, notwithstanding reference to a specific Section or paragraph of this Agreement.

SECTION 14.09Agreement for the Parties Benefit Only. Except as specified in Article XII, which is also intended to benefit and, to be enforceable by the Seller Indemnified Parties and the Purchaser Indemnified Parties, as applicable, this Agreement is not intended to confer upon any Person not a party hereto, other than the Parties successors or permitted assigns, any rights or remedies hereunder, and no Person, other than the Parties, their successors or permitted assigns, is entitled to rely on any representation, warranty, covenant or agreement contained herein.

SECTION 14.10Severability. If any term or other provision of this Agreement shall be held invalid, illegal or incapable of being enforced by any Applicable Law or public policy by a court of competent jurisdiction, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to a Party. Upon such determination by a court of competent jurisdiction that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to give effect to the original intent of the Parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.

SECTION 14.11Time of Essence; Action on Business Day. Time is of the essence in this Agreement. If the date specified in this Agreement for giving any notice or taking any action is not a Business Day (or if the period during which any notice is required to be given or any action taken expires on a date that is not a Business Day), then the date for giving such notice or taking such action (and the expiration date of such period during which notice is required to be given or action taken) shall be the next day which is a Business Day.

SECTION 14.12Construction of Agreement. This Agreement and any documents or instruments delivered pursuant hereto shall be construed without regard to the identity of the Person who drafted the various provisions of the same. Each and every provision of this Agreement and such other documents and instruments shall be construed as though the Parties participated equally in the drafting of the same. Consequently, the Parties acknowledge and agree that any rule of construction that a document is to be construed against the drafting party shall not be applicable either to this Agreement or such other documents and instruments.
